HEAVY-OIL VAPORIZER.

Application filed ,April 25, 1923. Serial No. 634,629.

1 The main object of this invention is to prov e a high y icien a hei' i y' practical device for vaporizing the heavier liqnid fuels such as kerosenaiclistillate, and the like, in connection with means to convey I orconduct .the resultant gas to a heater or heat retainer whiclrkee s'it in the gaseous state while ,being conveyed to a carbureter oriother'device for completing its preparation forcombust-ion. i A further object is to provide a device of this character .that includesa passagefor the products of combustionofthe gas it produces, so that these heated products of combustion are utilized for heating the'oil to the point of vaiporization and then keeping it vap' 'rized while passing through the heater ,to the carbureter. i A furtherobject is to provide a device of this characterthat is very compact, durable, of comparatively simple and inexpensive construction, and very conveniently opened or disassembled for removing incr'ustations or other detr mental accumulations which might result from the use of 'o'ils containing foreign substances.

However, a further object of this inventionis to provide for so thoroughly vaporizing the oil, that there will'be left no fresid ie'of oil in the vaporizerl c Other objects and advantages will .be pointed out or jimplied'in the following details of description, in connection with the accompanying drawings in'which:

i Fig. 1 is a vertical, centralsectio-nal view. Fig. 2 is a horizontal sectional view along the line 2 2 of Fig. 1. F is a horizontal sectional View along the'line 33 of Fig. 1. Fig. 4. isa detail sectional view along the line l4 of Fig. 1.

Referring to these drawings, in detail, in which similar reference characters refer to similar parts throughout the several views, the body of the vaporizer includes six pri marily separate sections (according to the present embodiment, though not of necessity), viz, sections 5, 6, 7, 8, 9, and 10.

However, the sections 5 and 6 are preferably made integral or united by brazing or electric welding'atthe plane directly above the line 3 "3I In likemanneiyfthe sections 7 and 8 are preferably brazed or electrically welded toone anotherat .thet'op of the's ection'7,

the latter'b'eing' preferably a hhllow cylincler,fwliile the members ,6 and S'Ta're .perforated or apertured disks or platesof sheet metal provided with .anniilar shoulders 6? andfi about which snugly fitjthe lower ends of the "sections 7' and 9 respectively. The tion 5am 9 r p e del th ap twred ears 11 through which'e gt'end screws or bolts 12. view of the foregoing, the deviices main body may be considerec'l as constituting, three separable sections held together by the screws 12, the section 10 in this connection being a removable part of the upper section 9-1'O, while the middle section 7'8 may also include heating'tubes 13 which are preferably rigidly united with the disk 8 by any appropriate means, it being shown that these tubes extend throughand are fitted in apertures indicated at 1% of the disks 8 and 6. However, thesetubesare removable from the apertures at '14 of the latter "or lower disk, sothat when the bolts '12 are removed, the ,uppe'r 'section 9-10 can first be removed from the middle section, andthen if necessary or desirable, 'therniddle' section can be removed from the lowersectioii 5'6 by withdrawing the tubes 13 from the lower apertures at 14, thereby gaining access to the gas-generating chamberwhichsurrounds the niain portions of the tub'es'l3. f T

For feeding oil into the gas-generating chambeig'l provide an oil-introd'ucingnozzle 15 for each one of the tubes '13, of which there are seven in the present instance, and these nozzles are'preferably connected with a single source of oil supply, as shown in my'applic'a'tions (referred to above). For this purpose I provide supply conduits which'preferably include US 16, unions 17, and flexible pipes 18, only oneof the latter being visi'blein'rig. 1, someof them--being hidden, and others being omitted. The nozzles 15 extend through the wall of the cylinder 7 and into relatively wide peripheral grooves 19 where they deliver the oil to be vaporized. The nozzles are preferably slotted or grooved across their ends, as shown at 15*, so as to feed oil even if the ends of the nozzles abut against the tubes 13, although it is int-ended that there be a slight space i the oil becomes thoroughly vaporized before it reaches the lower ends of the tubes, sothere is no residual oil in the bottom of the vaporizing chamber. It is to be understood that the oil is drawn into the vaporizing chamber in consequence of a partial I vacuum being created therein by the suction of the engine to which this device is attached or attachable, the intake manifold of the engine being connected to a conduit which includes an L or tubular oil vapor outlet 21 which extends through the apertured plate or partition 8 and has its outlet end extending into the exhaust gas outlet'22 of the section 9. The latter outlet forms part of a heating conduit or heat-retainer, so that the heat of the exhaust gas is retain-ed for keeping it from condensing while being eonveyed to the carbureter.

The oil vaporizing tubes 13 are heated by the heating fluid or exhaust gases or prod ucts of combustion which enter through an inlet or conduit 23 which may be either a part oi. or united with an internal combustion engines exhaust manifold. This inlet is part of the section 6, and the latter is formed with spreaders or angular ribs 24 and 25 each having its apex alined with the centre oi the inlet, so that as the exhaust gases enter, they are spread laterally in opposite directions for distributingthem equal ly among the heating tubes, while also de fleeting the hot exhaust gases upwardly towards and into the tubes. If these spreaders or distributerswere absent, there would be a tendency for the hot gas to pass by the tubes near the inlet, and piling up or aecumulating pressure at the farthest tubes, would impart more heat to these tubes than to the nearer ones, while also sending a relatively small amount ofthe hot exhaust gases through the tubes which are laterally disposed relative to the centre of the inlet 23.

' The sectionor plug 10 is merely a closure for an access open ng through which a brush or other article can be inserted for cleaning the interior of the tubes 13 through which the hot products of combustion pass from the lower section to the upper section of the vaporizer.

a It is not intended to limit this invention to the exact construction and arrangement hereshown and described, but changes may be made within the scope of the inventive idea as implied and claimed.

What I claim as my invention is:

1. In an oil vaporizer, the combination of a hollow body comprising an upper compartment, a lower compartment, and an intermediatecompartment, the latter having an oil inlet and an oil vaporizer outlet, the latter provided with an oil vapor conducting tube, this intermediate compartment having a tubular oil vaporizing member extending therethrough into open communication with the said upper compartment and lower compartment and into proximity to said oil inlet for receiving oil on its outer surface from said oil inlet; said lower compartment having an inlet for receiving a heating fluid which passes through said vaporizing member into said upper compartment; said upper compartment having a heating outlet which forms part of a heat-retaining pas sage and surrounds and encloses a part of said gas-conducting tube for the purpose specified.

2. In an oil vaporizer, the combination of an oil vaporizing chamber, a plurality of upright heating tubes extending through the interior of said chamber, a compartment un der said chamber and having a closed bottom under said heating tubes while its upper end is in open communication with said tubes, said compartment having an inlet for a heating fluid, this inlet being substantially horizontal, spread-ers extending up from said closed bottom and extending angularly thereacross and being spaced from said heat ing tubes so that a part of the heating fluid can pass thereover to the farthest tube while another part of the heating fluid is deflected laterally and upward to the nearer heating tubes, means to convey oil onto said heating tubes, and means to convey the generated vapor from the vaporizing chamber.

In testimony whereof I atfix my signature.

FREDERICK c. INDSEY.
